The first items to join the dollar menu will be the $1 Stackers on December 21.

"We believe passionately that people should have more than just the ability to eat for $1," said Chief Marketing Officer Marisa Thalberg. "They should feel like they can feast for $1. We are (and always have been) completely committed to coming up with the most craveable, creative menu items that set the bar for what great food at a great value should be."
